Adds the support for AMD EPYC Genoa generation processors. The model display for the new processor will be EPYC-Genoa. Adds the following new feature bits on top of the feature bits from the previous generation EPYC models. avx512f : AVX-512 Foundation instruction avx512dq : AVX-512 Doubleword & Quadword Instruction avx512ifma : AVX-512 Integer Fused Multiply Add instruction avx512cd : AVX-512 Conflict Detection instruction avx512bw : AVX-512 Byte and Word Instructions avx512vl : AVX-512 Vector Length Extension Instructions avx512vbmi : AVX-512 Vector Byte Manipulation Instruction avx512_vbmi2 : AVX-512 Additional Vector Byte Manipulation Instruction gfni : AVX-512 Galois Field New Instructions avx512_vnni : AVX-512 Vector Neural Network Instructions avx512_bitalg : AVX-512 Bit Algorithms, add bit algorithms Instructions avx512_vpopcntdq: AVX-512 AVX-512 Vector Population Count Doubleword and Quadword Instructions avx512_bf16 : AVX-512 BFLOAT16 instructions la57 : 57-bit virtual address support (5-level Page Tables) vnmi : Virtual NMI (VNMI) allows the hypervisor to inject the NMI into the guest without using Event Injection mechanism meaning not required to track the guest NMI and intercepting the IRET. auto-ibrs : The AMD Zen4 core supports a new feature called Automatic IBRS. It is a "set-and-forget" feature that means that, unlike e.g., s/w-toggled SPEC_CTRL.IBRS, h/w manages its IBRS mitigation resources automatically across CPL transitions.
